partition question

Hi,

When I type df -h i the following comes up:

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda3             6.7G  2.5G  3.8G  40% /
none                  375M     0  375M   0% /dev/shm
/dev/sda1              76M  9.2M   63M  13% /boot
/dev/sda4             103G  8.5G   90G   9% /home

Now what are the one mounted on /dev/shm?

Sincerely, Jorgen

Re: partition question

It is socalled "POSIX Shared Memory", a tmpfs. It's AFAIK used to allow multiple programs to access the same data in memory.
